This and othermodifications will be governed according' to the construction of the ginto which my invention is applied. My invention, it will be furtherunderstood, may be applied to practically all gins when firstconstructed, or it may be in the nature of an appliance to be attachedto various gins by simply removing the front ends of their casings. Ineither case it is evident that changes as to shape, proportion, andgeneral method of assembling the parts may be resorted to for adaptingthe invention to the peculiarities of the gins in connection with whichit is to be used. I desire it, therefore. to be understood that Ireserve the right to any such changes as come fairly within the scopeof' the invention and which may be resorted to Without departing fromthe spirit or sacrificing the efciency of the same.

Having thus described my invention, I claiml. A roll-board forcotton-gills, consisting of a plurality of fingers pivotally mountedadjacent to each other, and spring means for forcing the free ends of'said fingers in the direction of the saws.

2. A roll-board for cotton-gins, including a plurality ofpivotally-mounted fingers having curved surfaces, in combination withsprings disposed near the pivoted ends of the fingers and forcing thefree ends of' the latter in the direction of the saws, and means forobstructing the outward movement of the free ends of said fingers beyonda certain predetermined limit in the direction of the saws.

3. In a device of the class described, a casing, a plurality ofcurved-faced and flat-sided fingers mounted pivotally in said casingadjacent to and movable independently of each other, said fingers havingsockets near the pivoted ends thereof, springs seated in said socketsand bearing against a cross-bar of the casing to force the free ends ofthe fingers in an outward direction, and a cross-bar forming a part ofthe casing, to intercept and limit the outward movement of the free endsof said fingers.

4f. A roll-board for gins, including a plurality of pivotally-rnountedfingers and means for yieldingly supporting the free ends of saidfingers, the latter coperating to form, when in normal position, asmooth curved surface.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence ofl two witnesses.
